An intra-uterine speculum by Collin used to dilate the os cervix. Turning the screw retracts a central rod which is T-shaped in its distal part and so separates the blades of the speculum.
This type of instrument was originally invented by Brissez. Dating to the mid 19th century and of French origin this one is signed ‘Collin’ on the stem (a renowned Parisian maker of quality medical instruments). The octagonal handle is made from ebony, the shaft is made from polished steel and the blades of the speculum and the screw nut on the handle are made from German silver.
